Question

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet. What is Ruiz's percentage error?

A.0.6%
B.3.75%
C.3.9%
D.6%

Answer 1

3.9

Explanation:

16 - 15.4 = 0.6 ={0.6}{15.4} *100=0.039 * 100 =3.9%

Answer 2

Percentage error
`=(error)/(actual measurement) * 100`
Here error = 16 - 15.4 = 0.6
Therefore, percentage error
`=(0.6)/(15.4) * 100=0.039 * 100`
=3.9%
